ZZR1400 Geneology
Can anyone write me a few sentences to sum up the ZZR1400 family tree. All I know about this engine is that it's available, there's an MNR
happily buzzing around up the Scottish hills. I know nothing about its dimensions (or changes), or what has changed over it's (short)
lifetime.
Something like this, that I could say about the GSXR1000.
'The GSXR1000 (988cc) engine 2001-2002 (K1-K2), hit the scene originally with ca. 140bhp on tap. In 2003-2004 (K3-K4) the engine gained
additional injectors, a 32-bit ECU (from 16) and a few more bhp. The 750 from the same years shared the head, upgrades and wiring loom. Major revison
in 2005-6 (K5-6). Crankcase dimensions and mountings remained the same, though the block lost a little deck height and one mounting bolt. The clutch
became a slipper. Bore size went up, stroke down (998cc), strengthened rods meant no need to upgrade. Wiring similar, though ECU now chipped for a
key. Torque was down, power was up, and up the rev-range at 13,000 or so. This is regarded by many as the best engine of all years. The bike was
lively, lightweight (no real emmission gear), much wheelied. Resultant frame cracks/failures around th headstock mean the engines are readily
available.
Very major revisions came with the K7-. gearbox became a stacked item, the engine ending up 60mm shorter. New mountings will be required, oil pipes
for cooler now exit on the same side of the block, helping install. Electrics a good deal more complex. mainly emmission related, but still simple for
the racing man. Power now at 180 or so.
Oil surge has been an issue throughout the years, can be sorted with a dry sump (Nova item now no longer available). Baffle and shortened sump, will
work in some applications. Crank bearings go (no.3) followed by the rod. Engine, despite it's tendancy to self-destruct, is a good choice. If
you want reliability, the Blade is a better bet.

Why don't you ask the owner of the green MNR directly, that'll be Paublo999

This engine/bike only became available in 2006. ZX14 in the states, ZZR1400 in the uk so it doesn't really have that much of a history.
1352 cc four-stroke, liquid-cooled, DOHC, four valve per cylinder, inline-four
BorexStroke: 84.0 x 61.0 mm
CR: 12.0:1
DFI with 4xMikuni 44 mm throttle bodies
Peak power is around 9600 rpm at 165 bhp at the rear wheels on my car. Torque peak is around 7500rpm at just over 100lbs ft.
In 2008, refinements were made to improve the bikes rideability, raising power and torque slightly while they were at it. Changing injectors,
cyclinder head modifications etc.
Consensus is that it does not need a dry sump system, but I have an Accusump on mine just incase. Modified baffle/shortened sump is a must due to the
height of the engine. Stock clutch is good for car use, with the obligatory spring upgrades.
The engine has an artificial speed restrictor at 300kph and the immobiliser circuits can be troublesome, but I know solutions have been found.
A number of dealers/experts exist that will sell/assist you. Malc from Yorkshire has been working with these bikes for some time and Andy of AB
Performance will sell you a brand new crated motor for cheaper than the same year Busa.
I think it is a great engine and I definitely made the right choice. More modifications and help exists if you go Busa, but I wanted to be
different.
Perhaps not as accurate as your GSXR write up. Fire away with questions if you like and we will endeavour to answer.
Cheers
Paul.

Thanks Pablo, very much appreciated. I have extensive experience of GSXR engines, all flavours, the mass destruction of them mainly....
Were there any changes in the engine architecture (head/exhaust port dimensions/crankcase mounting points). i.e If I acquire a pre-2008 engine from
AB/Malcolm/Wherever and weld up the mounts and wire the thing in, is the post-2008 lump the same in wires and crankcase mountings?
What I have with the GSXR's is now a range of frames to take all engines 750-1300 K1-K7, I don't really want to add a huge number of ZZR
frames to this too. If it means staying post 2008, so be it.

Malc is the man to ask about mounting points. I have only ever seen two othese engines in the flesh. One rear mounted in a radical and mine.
From the write ups, I believe the modifications are minor and internal.
Fantastic engine. I just hope mine can take another year or thrashing before it needs work. 
Cheers
Paul.
